| Abstract: | Combustion-supporting additive of pulverized coal is an important measure to improve the combustion process of pulverized coal in the blast furnace injection conditions.This paper mainly studies the effect of anthracite and bituminous coal with different proportions of MnO2 on its ignition temperature,explosiveness and heat productivity and meanwhile makes a comparison and analysis on the respective influence of the three test samples on coal combustion characteristics.Meantime,the optimum adding ratio of MnO2 to different test samples is certified. |
